Be it known that SAMUEL MANNiNo, a citizen of the United States of America, and a resident of the city and county of Albany, State of Nemi York, have inventedcertain new and useful improvements in Apparatus for hixing Fluids, of which the following is a specification.

My invention relates to apparatus for mixing fluids; and the object of my invention is to provide a mixing-receptacle by means of which the hot and cold Water to be used, especially for bathing purposes, may be mixed, so that the proportion of Water from thc hotwater intake to that of the cold Water from the cold-Water intake will be accurately determined and when regulated will remain the same until changed bythe operator, and such other elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish this object by means of the mechanism illustrated in the accompanying drawings, in which" Figure l is a front elevation Wit-h parts broken away. Fig. 2 xs a section along the lines il" lV on Fig. l. Fig. 3 is a section along the lines X X on Fig. Fig, -1 is a section along' the lines Y Y on Fig. 2. Fig. 5 a section along the lines Z Z on Fig. l. Fig. 6 is a developed View of the outside of the cylinder ,B parted at Q on Fig. 3.

Similar characters refer to similar parts throughout the several Views.

The casting A is pi vided with the ports l, 2, 3, and The port 1 may be the inlet for cold Water, the port 2 inlet for hot water, port 3 the outlet for shower-bath. the port '-i outlet for hand-spray,

Nithin the casting A, l place a` plug B, preferably making a` tapering ground joint with the interior of the casting A, although l. do not limit myself to that arrangement oll joint or connection, since it may be cylinder fit or packed, as desired, In the plug B, I proyide the openings l), D', and E. The openings D and D are preferablytapered-thal is, Wider at one end than at the other, as shown in Fig, 6Min such a manner that when the plug is revolved, so that the opening l) or D registers with either the cold or hot water intakes, the amount of the water admitted will depend upon the position of the opening D or D" which is in register with said intakes.

The port E allons foi-thc discharge through the ports 3 or Ll in the casting A. i

The plug B is preferably Fprovided with a central hub F F igs. 2 and 5, to which is secured a handle G and a polnterfl. The handle and pointer may be secured to the hub 1n any suitable manner by means of a plate f 6o and holt f, as shown in Fig. f2, il desired.

l place a cap K, which is preferably provided with boss )'r, adapted to engage with the front of the plug B, as shown in Figs. 2 and 5, and with a threaded flange K', adapted to engage with threads on the casting A, as shown .in Figs. 2 and 5, whereby the cap may' be secured in place, the ness engaging the plug forcing the plug to the desired position Within the casting and holding it in position there and the cap prevented from turning by means of a set-screw L, Fig. Over the cap I preferz'ibly arrange a dial N, which may be secured to the casting A by screws n n, as shown in Fig, 5, or in any suitable manner.

It is understood, of course, that the cap K and the dial N are placed in position before the handle G and the pointer l are secured to the hub. On the dial I'preferably place the letters Olf,"7 which in Fig. l are at the top of the dial and indicate when the pointer J points toward theni that no Water is admitted into the plug B, the letters C C on each side of the word Ulf indicating when the pointer points toward either of them that cold Water is delivered to the plug B, the letters M l M indicating when the pointer points to them that water of medium temperature is delivered `to the plug, and the letters ,ll ll will indicate when the pointer points toward either of them that hot Water is admitted to the cylinder.

As thus arranged when the plug B is in thev position shown in Fig, 3, the openings l) D therein out of register with each oi' the intakes l and 2, no water is admitted to the plug7 and the pointer in this )osition will be toward the letters Oli. Should the plugbe rotated toward the left, the pointer would then move to the osition indicated by the letter t on the dlal, the openi'ngl' would register with thi` cold-water opening l, and the cold 'atei' would be discharged through the opening E and the shower-port 3. if th(` plug is rotated from the position shown in Fig. 1 to the right, to the point indicated by C, the cold water would be admitted to tho plug, and the port E of the plug would register with the port 4, and cold water would be discharged through the hand-spray. Vhen'theplugis rotated to any position between C and l-l (indicated generally by M in either direc- IOO IIO

tated to the left in the positiongindicated by 11, hot water would be delivered to the shower, ,and if it were rotated to the right to the osition indicated by H hot' water `wou d be delivered to the hand-spray.

I preferably arrange upon the dial the projecting lugs P'P, which are' stops projecting lin the path of the movement of the pointer and prevent further movement of thepointer, and therefore further rotation of the plug.

By making the openings D and D narrower at one end than at the other and graduall tapering I have arranged for admitting eitier a small or a large stream of water and gradually increasing or diminishing the volume when desired by rotating the plug, and it is for this reason that l say that in any position between and H both hot and cold water will be admitted, the degree depending upon whether the wide or the narrower portion of the openings D and 1)/ registers with the intakes.

in practice I preferably arrange my device so that the cold water will be admitted through the full opening and later on the hot water through the contracted opening and gradually increase the latter and decrease the former simultaneously and at the same time adrnittingto the shower or to the handspray, according to the direction of rotation.

The stops l and P may be located so that the pointer shall 'engage them before the hot water is admitted at the full opening, and therefore before the cold is entirely shut oil, und thus alldanger of scalding vmay he preven t ed ln my arrangement of the mixer theparts are easily removed and readily put together. There is an entire absence of springs and other parts that weaken or deteriorate in their usage. rThe manner of securing the cap to the casting and at the same time by means oi' the boss on the cap adjustin .the

novel arrangenn-mt.

What l claim m invention, and desire to secure by Letters Iatent, is

1. In a device Jfor mixing fluids; a casting provided with an intake for hot water, an incvlinder is a *very satisfactory and, I t ink, A

take for cold water, and two outlet-ports; a plug in said casting provided with a port adapted to register with either outlet-ports, which one dependingupon the direction the plug is rotated, and also provided with two tapering openings, havinrr the smaller ends of 'g y said openings toward .each other g a space between the smaller ends of said openings; a space between the ends et .the enlarged portions of said tapering openings, whereby the distance remaining between the ends of the tapering openings will' allowl for the side of the plug between the openings to not only act as a closure for the hot-water intake when the plug is in a single position, but to maintain said hot-water intake closed duringla portion of the time ther plug is rotated 1n either direction, the space between the ends of the enlarged portions of s aid tapering openlngs suiiiciently great to act as a closure for the cold-water port, but which will revister with said cold-water port when the ug is rotated in either direction before the otwater port will bev opened; the continued movement of the plug in the direction in which it is rotated causing a decrease in the flowof cold water and permitting the-inflow of hot water, dependent upon the extent to which the plug is rotated, until the cold-water intake is 'closed by the side of the plug bei tween the narrower portions of the said tapering openings, registering with the cold-water port.

2. A device for mixing fluids, comprising a' casting; a'plug adapted to rotate therein;

said casting provided with va h0t-water-in take, a cold-water intake and two outletports; said plug provided withan opening adapted to register with said outlet-ports', re-

spectively, which one depending upon the d1- rection of rotation of the plug, 4with gradually-contracted o enings adapted to register with the said inta (es, all so arranged that by the rotation of the )l ug in either direction the cold water rmay be delivered through an outlet-port without interruption, and when the plug is further rotate( the amount of cold water will bedecreased,and the amount of hot water increased, simultaneously and gradually.
